Inter-vehicle communication protocols for multimedia transmission

Abstract

Vehicular Ad Hoc Network (VANETs) could achieve flexible communication among vehicles and with infrastructure. VANET provides multi-hop transmission to cover all intended receivers. This multi-hop capability has the potential to increase safety, efficiency and convenience of transportation system. Multi-hop transmission enhances a range of applications including traffic safety and comfort of every day road travel. In most of the envisioned applications, information to all or specific group vehicles inside a certain region is needed to be delivered. These applications rely on unicast, broadcast and geocast approaches. This study presents a review of recent routing protocols for both text and video data transmission. In particular, this paper focuses on quality based comparison of routing protocols for video data streaming over VANET. Some of routing challenges for video streaming and text dissemination over VANET are also discussed.
